My invention relates to presses and in particular to a press-for thebaling of paper or other finely divided and fragmentary material. i

. It is the object ofV my invention to provide a press of this character Which .Will rapidly bale the material in question, which may be readily assembled and which Will lhave suit- -able safety devices to insurecontinuous operation Without breakage inthe event foreign material is introduced in the press-inadvertently.

VIt is myobject'to provide apress so arranged that the feeding board Will be maintained substantially vertical'during its descentl into Vand its ascent from the baling chamber to prevent the Withdrawal of material fromthe the chamber :which .been fed into it.

AIt is my object to "provide means for this purpose for' preserving the feeding board in nearlya vertical :position from the connectingl bars between the upper end of the feeding board and fixed points-on the general frame Where the other ends bars are pivoted.

of the connect-ing Itis my object to provide such'an arrangep ment so tliatthe distance between the pivots f ao of the connecting bars and the pivots of the feeding arms is greater -at the end near the feeding board than the distance between the pivots of the connecting arms and the feeding arms at the other end of the bars and arms.

It is a further object to provide means for releasing the feeding board from further movement Whenever the board is obstructed in the act of feeding as by some solid object found in the paper or other material that is being fed into the baling chamber.

It is my object to provide such a safety mechanism Which is novel in that, although the safety springs increase incompression as the power is continued to be applied, still l` the leverage over the springs increases at a greater ratio than the compression increases which results in relieving the feeding board p n n i'rom any .increased pressure against the ob struction although the coil sprngsalle dergoing further compression.

to provide a built-up steel `construction of Mysafety device `is soarrangedv that this increased pressure on the feeding board is prevented ev-en vthough the press continues to Voperate during the time that the obstruction is in anV obstructing position. 4 y

Itis a furtlierobject to provide means in a bearing mechanism for maintaining the driving andjdriven shafts in suitable alignment and for aligning themeasily When the machine is assembled., which greatly reduces the necessity for careful manufactureand the expense thereof. i

, Itis an additional object to 'provide a novel feature of construction ofthe vfra-me in that "side plates extend from the bottom of the machine above the upper rail Where they are used as' supports for the bearings y of the shafts, vboth .for Vthe driving shafts" and the p driven shafts. I Y

Itis an additional object of myinvention to provide` a novel form of retainer dogs v`for retaining 'the division block, which.' consistsV of aplurality of dogs mounted on a common vertical shaft, Which is indep'endentlyfactuated and adjustable. f n It is an additional feature of my invention to provideadjustable Wearing plates for the cross head, of replaceable and detachable material. y l

It is an additional object of my invention to, provide a four-Way adjustment of the Walls 'of the reary portion of the baling y chamber.`

It is an additional object of my invention the plunger or plunger head and in particular'to provide a novel form of plungl head A.which can be easily andV cheaply manufacturedybut which Will have requirements of strength and ease of replacement not heretofore obtainable. In the accompanying drawings: "Figure l is a top plan vievv of the complete press; i 1 1 p Figure 2 isa side elevation of the complete press with the feeding board in its fele vated resume; i 'i' Figure 3 is` a longitudinali section taken von a vertical plane through the baling endjofr;

`"bottom plate :6. This pl'ate is Lfurther're-inforced by plurality of transverse angle irons, 7, 8 kgand k10; ',Sidefrails'll and 12 'of'pla'tea're provided on this support, longitudinal, upon which members, llraiid 12,

are the angle irons or rails 13 ian-d 1'4'rwhich are supported and bolted 'by the bolts 15. To these lower rails, 13 and 14, are boltedby the bolts 16, the side plates 17 and 18. These `fsideplates"extendupwardly withinand above upper-rails 19 and i2OY which lareboltedthereto by the bolts 21. 'These side plates are capped 'at their upperHen-dby a'plate-22. V2?). de'si'g- Vnates a vdriving pulley which isfdriv'en yby a belt 'from any lsuitable"source of power. This pulley is mounted upon the driving shaft 24 which carries the driving pinion 25 which drives a driven gear 25a on the driven shaft v 24a. 0n the other end of the shaft 24` is a fly wheel 26. The lsha-ft 24a isijournaled in al plate 27, thel innerv margins of which rest upon' the Ashoulders 28 of the side plate. -As r'these side plates are roughly formed and as the disks 27 are-likewise `relatively roughly formed, it may ,result ,that the driving shaft is not in its proper position in a suitable horijzontal plane. In order to prevent the necessity for a heavy, perfectly manufactured structure lfor this purpose which would be prohibitive in its expense, I provide therfolv'lowing arrangement fora'djusting this driv- `ing shaftjin its-horizontal plane, so that it vwill turn in iits bearings 29 yin the planedesired. Y l

The disk 27 is provided Vwith Yflanges 30. having concave faces 31.1 Betweenthis con- Vcave face and the side plate is a' wedge 'disk d '32having a wedgemargin with a-convex surface 33. f This disk is provided with slots'internally disposed; designated 34; through 'which the bol'ts'35 pass -for retaining the several members together in position on the f'side plate. Thus, if it is desiredto Achange 'the angularity of the driving shaft to the lhorizontal plane, ashiftingof this wedge plate upwardly or ldownwardly l will 1 effect the rdesired end. Bolts can vthen befclampedand the structure `will be hel-d in the desired'posil tion. f

spaced pinicns-Sdiheld inpositionfby'the lneys 37 in the conventional 'way. l These'pinions engage withvr their respective gears 38.

These gears are 'mounted onsuitableshafts carried by y-the'side plates, aswill be more fully seen in Figure 6. The` gears 38'jare j lrnownas the pitr'nan lgears. They are mounted upon a bearing sleeve 89 "over theV end of whi'ch'is a plate 40 bolted to the gear by the 'boit-S411. A receiving cup 42 onthe inside of this'plate receives a square shaft 43,`the other end 'of which turns in a bea-ring 44 on the 'interior of the plate'45 which'carries-thevstud shaft 46 for supporting the gear and its bearing 39. This square shaft 43carries a'retaining cotter or sleeve v47. The plate 45 isbolted toftheside plates by the bolts 48.

@n the `rini-o-f each gear is an aperture 49 carrying theend'of a'crosspin 50, von which is journaled a pair, of plates 51constituting. the pitman. These Vplates 'are bolted togeth- -v er fby the bolts '-52. Asimilar arrangement is found at the other end 0f the pitman which are bolted together the bolts 53 on a sleeve I54mounted on a cross pin 55"'whicli isjouriale'd in the bearingsl 56 and bolted the bolts V517 on the vertical. plates 58,.:which constitute a portion ofthe plunger. f This construction will' beseenin F igurel i These plates 58 are' providedwith outwai'dc. rlhe U-shapen member` 62 is provided with shonlders 64 which lit on either side of the' flange The top flange 59 has supported thereon a top plate for the plunger 65, which es with the wearing plates 66'. These wearing plates are preferably of wood and are suspended by the bolts 67 from the cap plate 68.

The end of the plunger head is formed by a steel plate 69 connected to the vertical side plates 58 by.internallyidisposed angle irons 79 bolted to theplate 69 in the plate 58 by the bolts 71. This provides a light weight but extremely strong assembly and disassem bly structure. It is a matter of greatadvantage to have a built-up structure orF this character with a steel built plungerhead.

AMounted on the interior `of Vthis plunger is a linlr 72-pivoted at 73' on the plunger, and at its other end 741 to the curved endV 75 ol a driving arm 76. This drivingarm is carried on bracket 77 which, in tuin, is

pivoted upon a cross shaft 78 carried in the bracket T 9 on a transverse portion 8O `ot the housing which is connected to the side plates et the frame. @n this. same transverse pin 7S is pivotally mounted the lower block arm 8L the outer end of which is'curv'eddownn'ardly at 2 to a point where it ispivotally mounted uponthe cross shelf-n.83 carried inthe Abracket 84 on the feeding board rllhe upper end of this braclret 84 ,carries a second pivotal memberSG to which isconnected a spacing linlr 87, the other end of which is pivoted at .88.on a braclret 89 cai'- ried on the 4same transverse portion 80.

The 'feeding blocl: is provided with a pair of downwardly extendingand diverging segregated feeding lingers 90.v 'A follower niemher 90a is provided on the one face of the feeding board. i

ln order to prevent injury to this mechanism. it' the end ofthe feeding board comes in contact with an object which cannot be compressed. kas .in-Figure 4, it' will be noted that the drivingarmf'tl carried on the end thereof pivot-ally at 91, a frame or link 92, the upper end of which is pivoted at 93 to a second frame 94, the other end of'which is pivoted at 95 to the arm 81. Between the pivotal vpoints 91 and 93 is a cross pin 96 on which is mounted the eye 97 of a pin 98, the other end of which carries a nut 99 and washer 1GO '.lor engagement with a helical spring 101 surrounding the pin 98 and having its otherend engaging upon a washer or plate 102 nionnted on the frame member 94. V103 is a stop member carried by the arm 81. .f

When this block is moved downwardly,l if its movement isresisted bypan obstacle, such as 1011, while the machinery continues to move, thearm T6. will continue in its down ward movement 'and in doing so will tendf" to pull baclrwardly and downwardly the member 92 and themember Qdfwhichare pivoted together :11193; The movement of 921 is resiste-d by the eccentriclbolt 108. It will be notedrthat, due to this arrangement, the leverage will continue to'increase while the spring resistance will not proportionately increase so that the strain upon theV feeding board will not increase, due to the increase of from-the dead center.

The division block 105. is dropped into the lhopper 19S through which vmaterial is introduced to be compressed into the baling chamber 197 by thellshaped, division block sup'- po'rts 108 which is pivoted on top of the balingchamber at 11.09and is actuated by a lever or levers 110, These supports 108l are spa ced to support theedges of the block. The blocks are heldin'position as they'slide into the hopper by vthe. guides 111 `which f are mountedon the slides108'. It will be noted that these division `blocks are provided with fa central. member y112 and spaced keystone 'ieinbers 113 on. either side thereofV which have slots of tapered cross section designated 11el .therebetween with the narrow end of the slot on, the outside, This providesfa space through `which lthe wiresmay be inserted. e

In controllingthe starting and stopping of the machine, l provide'a clutch lever 115 which carries a li'nlr 1.16 pivotally connected topa bell crank .117 which is pivotedV on a bracket- 118 on the vtrame. `v'The other end of this belll crank` is connected Yto a clutch of lll() l anydesiredflind119, which connects Vthe power frointhe pulley to the Ydriven shaft 24, as desired.

mounted7 extends across the machine and on the other side carries afbraclret 121 which. engages with the peripheryoi the ily wheel llt'will be noted that the construction of the actuating mechanism for the feeding :block consists of a pair of Varms 76, a pair of arms 81 anda pair oi' springs 101. Sach-anarrangement gives a/steadier machine and ini snres that the bloclr will bemaintained in its predetermined pos fions. j

Turning to the rear end olthe baling chamber and in Aparticular.to Figures ,18 and 15, it will .be noted that aplurality of` slots 122,

The shaft 120, on which the lever is {l1-l5 yione above the other -on leither side-'of the machine inthe `side walls 123 ofthe baling chamber.V Through these slots project the tapered Vnosesf12t'on the retaining arms or retainer dogs for retaining the division block. These retaining dogs-.125 on each side are mounted on Aa common `verticalshaft 126 which hassupporting eye`s'127 on plates 128 attached-.by the bolts 12551 to the side walls 123. The l outer 'endsof lthe dogs are provided with eyes 130 into which is hooked IIB a helical spring 131, the-other lend -of'which is mounted on 'a U-shaped lbolt 132 that/is adjustable through the 'nuts 133V in `its position to adjust the tension of the spring 131. These :bolts pass through af-bracket 134` on the outside of the sideV walls 123. Thus, the groups 4of'retaining dog's are adjustable but are supported upon fa `common vertical shaft on their respective sides in their respective series. f

,The rear end of the 'blaling chamber 'has mounted `on the sides thereof,jspa;ced from one another, a 'pair 'of plates 135. These plates are mounted upon supporting members whichare T-shaped, designated 136, the flanges `of whichare connected by bolts 137 to `lll-shaped members 138carried on the screw 138. This screw turns in acotter 140 which has eyes 141-1 in which are pivoted the links 142. These links are pivoted at theirot-her Aends 143 V.to the cross members 144 lat the top and thecross members 145 at 'the bottom. These cross members carrybottom plates 146 and :top plates 147 to which they are bolted by the bolts 148 and 149. Side flanges 150 and side plates 151 are'carried thereby. y

VA similar screw construction is carried at either `end. .The ends of these plates 135 ,extend outwardly 'and parallel gto the baling Chamberland are 'mounted upon the ends of the stationary side plates 123 of the fbaling chamber and 'areV heldin position on the bolts .152 by the helical spring 153 Vsurrounding the bolts. y Y 4 r)The other ends of the plates 135rare supported by the construction shown in Figure 9, consisting of the screws 139 vandassociated mechanism. The top Aand bottom plates 146 and 147, are thus adapted fto be drawn together simultaneously by the 'drawing .together or expansion of the side members 135, so that Vthe pressure is equalized on all four sides, strains are relieved land the size ofthebaling vchamber is adjust-able. rThe bracket arms 1511 carry a delivery Vplatform 1.55, at the exit end of the baling chamber.

The synchronismof the dropping of the spacer block or division block is effected through a pitman 156 which is mounted on the crank 157V on the shaft 43. Its other.` end is provided with a slotted portionz158 which works ona pin 159 connected Vto fa .lever-160 moge-2a i which.; is fmounted on the shaft Q-vof the division' dropper 108.

T he lpower is applied `to the pulley wheel 123 which is communicated to the drivenshaft 24 which` turns the pinion 25. yThis result-s jin Vdriving the gear a, the driven shaftl 24a,

-tlieg'pinions 35,')thegears 38, the pitman 51,

are varied due 'to the fact that the link 87 j is a straight linl; .and link 81 has a curved fend A82 which is connected to the lower portion ofthe feeding board. VThis permits of the straight down feedingof material into the chamber and the vwithdrawal in a substantially straight line of the feeding block to prevent pulling lthe material out again.

n 1n. the event of wear, due to the thrust of the plunger upwardly against vthe top of the machine, the 'wearing blocks of wood canbetaken away and new ones replaced. The bottom oftheV plunger is carried on rails so that the friction at that point is thus taken care of. f

The, safety l device. has already been described;Y In' Vthere/event of stopping of the Hfeeding board, the machine can continue to 'operate without having 'any damage or eX- cvess forceapplied tothe'feeding board or vassociatedmechanismV due 1to the give of the spring 101 andthe Uyshaped toggle mem- "bers'92 and 93 which work one within the other between. the pairs of arms 81 and 76.

It will, be lunderstood that the means of adjusting the horizontal position of the driven shaft is also used in connection with the Vdriving shaft. It can be used with the other shafts, as desired. Y It will be also understood that I desire-to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses.
